Some of these cells make up glands
Epithelial tissue or epithelium
Epithelium consisting of one layer of cells, which all rest on the basement membrane
All may not reach the apical surface
Simple Epithelium
Epithelium of a single layer of cells that is very thin, typically allows the passage of materials by diffusion (is permeable)
Ex) Kidneys, alveoli in lungs
Simple Squamous
Epithelium of cube shaped cells in a row, important for absorption and secretion.
Ex) Kidney, ducts of glands
Simple Cuboidal
Epithelium of tall blocks in a row, important in absorption
Ex) Digestive Tract, Bronchi in Lungs
Simple Columnar
Epithelial layer where all cells rest on the basement membrane but not all reach the surface
ex) Trachea, respiratory epithelium
Pseudostratified
Epithelium consisting of 2 or more layers, not all touch the basement membrane and not all touch the apical surface
Stratified Epithelium
Stratified layer often used for protection
Ex) skin (keratinized), moist linings like the mouth (non-keratinized)
Stratified Squamous
Stratified layer that often stretches and is transitional
Ex) Urinary bladder and uterus
Stratified Cuboidal
Stratified layer that is also for protection. Rare in the body.
Ex) Large ducts of glands, male urethra (UTI)
Stratified Columnar
Glandular epithelium with no ducts, into the blood
Glandular epithelium with ducts
Endocrine
Exocrine
Tissue that connects things in the body, and is also a packing substance
Connective Tissue
Specialized connective tissue does two things…
Support the body
Transport O2 and CO2
